the wind pressure is one of the important loads on cooling towers which can be computed via numerical solution of the wind flow. in this paper, the effects of turbulent modeling on accurate computations of wind pressure on a cooling tower with base structure are investigated. for this propose, the results of a finite element flow solver using various commonly used turbulence models are compared...

In this paper solar assisted heating and absorption cooling system and domestic hot water needs for a hotel having fifty rooms in Antalya have been investigated. First of all, solar radiation and meteorological data for Antalya and heating and cooling loads of the hotel building are given. For the heating cycle, active systems using liquid as the working fluid; and for the cooling cycle, solar-...

BACKGROUND AND PURPOSE Therapeutic hypothermia represents a promising neuroprotective treatment for patients with ischemic stroke. Selective, intracarotid blood cooling may initiate rapid and early brain hypothermia, reduce systemic effects, and allow combined endovascular mechanical thrombectomy. For this approach, a balloon cooling catheter system was designed and studied in vitro to optimize...

Biomass gasification is the process of converting biomass into a combustible gas suitable for use in boilers, engines, and turbines to produce combined cooling, heat, and power. This paper presents a detailed model of a biomass gasification system and designs a multigeneration energy system that uses the biomass gasification process for generating combined cooling, heat, and electricity. Energy...

Performance and economical efficiency of the combined cooling, heating and power (CCHP) system mainly depend on the system structure, operation strategy and choice of facility capacity. This paper proposes a structural configuration of the CCHP system with hybrid chillers, consisting of a combined electric and absorption chiller, whose electric cooling to cool load ratio varies according to dif...

Improving the cooling efficiency of servers has become an essential requirement in data centers today as the power used to cool the servers has become an increasingly large component of the total power usage. Unfortunately, most previous approaches have individually focused on reducing either the server power or the power used by the fans to cool the servers. This paper presents Zephyr, a syste...

the present article focuses on the evaluation of a first-moment closure model applicable to film cooling flow and heat transfer computations. the present first-moment closure model consists of a higher level of turbulent heat flux modeling in which two additional transport equations for temperature variance kθ and its dissipation rate εθ are considered. it not only employs a time scale that is ...
